Preferably, the chambers are formed with beads or ledges 29 substantially at the junctures thereof with the longitudinal run of the smoke duct to form seats for the cartridges. and to retain the same within the chambers I'i and I8 above the longitudinal run 20a of the smoke passage and the outlet 25.

Means 30 are provided for normally closing the open ends I9 of the filter chambers Ii and I8 and establishing, as a result of the closure of said open ends I5, which constitutes a vent into the smoke passage, communication between saidV chambers and through the smoke conducting passage 20 as a whole. Said means 3D, as one example, comprises a tubular bridging member or yoke 3l having angularly directed tapering op-en ends 32 fitting into the tapering openingsY I9. The member 3l is preferably carried by stem or member 33 slidable in a plate or abutment 34 secured within the enlarged end portion 35 of the recess 36 provided in the extension I 6 between the chambers I 'I and I8. The lower, round portion of the stem 33, within they recess 36 and below the plate Sicarries a coil spring 37 retained therein by the abutment 38, and normally serves to retain the member 3| retracted and in position engaging said openings I9. Preferably the upper end 35ia of the stem 33 is made polygonal in cross section to prevent rotation thereof within the plate 35 and to insure the member 3| being aligned with the openings i9 to properly Yengage therewith when the member 3l is released rand permitted to return to normal position. If so desired, as shown in Fig. 5, the member 3 I, in the released or engaged position, may be housed within a suitable recess 39 formed in the top of the extension Wall I6 to prevent undue projection of said member 3| above the top of the pipe.

As shown in Fig. 6, the ascending and descending portions Il and I3 of the smoke conducting passage 20 constituting the absorbent receiving chambers may be communicatively connected contiguous to the open ends I9 thereof by a transverse or connecting passage portion 4D formed in the extension It itself. The open ends I9 may then be closed by a'member inthe form of a plate or disk il preferably seated within a recess 42 formed in the top of the extension. I6.

The plate or disk il is yieldingly retained seated by the spring mounting d3 like that described above and more fully illustrated in Figs. 1 to 4. The disk 4I is preferably provided with a finger piece Sla for enabling the same to be lifted in order to insert or remove the absorbent elements 28 into or from the chambers I'I and I8. The plate or disk I, like the member 3l), serves to close or seal the entrance I9 to the cartridgereceiving chambers. By sealing this vent I9 into the smoke conducting passage 2G, communication is established therethrough, rendering the passage operative for smoking.

In operation, the member 3I or 4I may be readily grasped bythe finger piece 3 ia and raised against the tension of the spring 31 to clear the openings I9 and allow the insertion or removal of the ltering cartridges 28 into or from the chambers I'I and I3. When the member 3I or 4I is released, it closes or seals the openings I9 to establish communication through the passage 2U from the bowl I El to the discharge end of the pipe. The smoke in being drawn through the pipe traverses the succession of filtering or absorbent elements 28 which remove the distillates, oils and' and the contamination of the absorbent material `by the tobacco or by the ash resulting from the combustion.

In my invention the cartridges 28 may be readily inserted into and removed from the offset chambers I'I and I 8 by a simple operation, rendering it unnecessary to remove the bit 24 as in types of pipes having a filter in the longitudinal run of the smoke duct or bore. The pipe is also fully operative for smoking when the absorbent elements 2B are removed.

By my invention I am enabled to obtain a sub-- stantially dry smoke without impairing the normal operation of the pipe or unduly complicating the structure thereof. By the provision of the plurality of cartridge receiving chambers formed in the wall of the bowl as described, the absorbent path is substantially extended or lengthened without unduly increasing the size of the pipe.

Having thus described my said invention what I claimand desire to secure by Letters Patent is:

l. A smoking pipe comprising a bowl, .a stem portion extending therefrom, the wall Vof said bowl and said stem portion having a smoke conducting passage therein including ascending and descending portions in said wall open at the outer ends thereof, a tubular bridging member engageable with the open ends of said ascending and descending portions for establishing communication therebetween, and resilient means disposed within said wall and connected to said bridging member for retaining the same in engaged position.

2. A smoking pipe comprisinga bowl, a stem portion extending from the bowl, said parts having a smoke conducting passage therein including relatively enlarged ascending and descending substantially vertical portionsY formed in the wall of said bowl in spaced apart relation and open `at the outer ends thereof, said wall between said ascending and descending portions having a recess therein, absorbent elements disposed in said ascending and descending portions, closing means for establishing free communication between said ascending and descending portions beyond the outer ends of said absorbent elements, and resilient means disposed insaid recess and connected to said closingmeans for yieldingly retaining the same in closed position. Y

3. A smoking pipe comprising a bowl, a stem extending therefrom, said parts having a smoke conducting passage therein including relatively enlarged ascending and descending portions formed in the wall of said bowl in spaced apart relation and having openings at the outer ends thereof substantially in the same plane, said wall between said'ascending and descending portions having a recess therein, absorbent elements disposed in said ascending ,and descending portions, a tubular bridging member engageable Vwith said open ends for establishing communication between said ascending and descending portions,

and resilient means disposed in said recess and connected to said bridging member for retaining the same in engaged position.

4. A smoln'ng pipe comprising a bowl, a stem portion extending from said bowl, said parts having a smoke conducting passage therein including relatively enlarged ascending and descending portions formed in the Wall of said bowl in spaced apart relation and having openings at the edge of said wall, said wall having a recess formed therein between said ascending and descending portions substantially in alignment therewith, closing means for said ascending and descending portions at the open ends thereof and serving to establish communication therebetween, and means within said recess connected to said closing means at an intermediate point thereof for yieldingly retaining said closing means in closed position, said last named means being mounted to .allow rotation of said closing means, when the same is lifted, to a position at right angles to the closing position.

5. A smoking pipe comprising a bowl, a stem 'portion extending therefrom, the wall of said bowl and said stem portion having a smoke conducting passage therein including ascending and descending portions in said wall open at the outer ends thereof for receiving .absorbent elements, a member serving to cover the open ends of said ascending and descending portions and establish free communication therebetween, and resilient means disposed within saidl wall and connected to said member for retaining the same in engagement with said wall.
